Pertussis, commonly known as whooping cough, is a highly contagious respiratory infection that affects people of all ages but is especially dangerous for infants and young children. Despite the availability of vaccines, pertussis continues to cause outbreaks worldwide, making awareness and timely prevention critical.
In this blog, we will explore the causes, symptoms, complications, prevention, and treatment of pertussis, along with its importance in public health.
What is Pertussis?
Pertussis is a bacterial infection caused by Bordetella pertussis, which attaches to the lining of the airways and releases toxins that cause inflammation and mucus buildup. This leads to persistent coughing fits followed by a high-pitched “whooping” sound when the person breathes in.
Symptoms of Pertussis
The disease progresses in three stages:
- Catarrhal Stage (1–2 weeks):
- Mild cough
- Runny nose
- Low-grade fever
- Sneezing
Often mistaken for a common cold.
- Paroxysmal Stage (2–8 weeks):
- Severe, frequent coughing fits
- “Whooping” sound during inhalation
- Vomiting after coughing
- Fatigue after episodes
- Convalescent Stage (weeks to months):
- Gradual recovery
- Cough decreases but may recur with respiratory infections
How is Pertussis Transmitted?
Pertussis spreads through respiratory droplets when an infected person coughs or sneezes. It is highly contagious, and one infected person can spread the bacteria to most unvaccinated contacts.
Complications of Pertussis
Pertussis can lead to serious health problems, especially in infants under 12 months:
- Pneumonia
- Seizures
- Brain damage due to lack of oxygen
- Dehydration
- Death in severe cases
In adults, complications may include weight loss, hernias, and rib fractures from intense coughing.
Diagnosis of Pertussis
Doctors may confirm pertussis through:
- Medical history and symptoms
- Nasopharyngeal swab (lab test for bacteria)
- Blood tests for antibodies
Early diagnosis helps in controlling spread and reducing complications.
Treatment of Pertussis
- Antibiotics: Most effective if given in the early stage.
- Supportive care: Includes rest, fluids, humidified air, and oxygen if required.
- Hospitalization: Often necessary for infants and severe cases.
Prevention of Pertussis
The best protection against pertussis is vaccination.
- DTaP Vaccine: Given to infants and children in multiple doses.
- Tdap Vaccine: Booster recommended for adolescents, adults, and pregnant women (during every pregnancy).
- Cocooning Strategy: Vaccinating family members to protect newborns.
Good respiratory hygiene, like covering coughs and washing hands, also helps reduce transmission.
Pertussis in Pakistan and Worldwide
Despite global vaccination programs, pertussis remains a public health concern. According to the World Health Organization (WHO), millions of cases occur worldwide every year, with infants at the highest risk. Strengthening immunization coverage and awareness can significantly reduce pertussis-related deaths.
Key Takeaway
Pertussis (whooping cough) is more than just a persistent cough—it can be life-threatening for infants and cause complications in adults. Vaccination, early diagnosis, and preventive strategies remain the most effective tools in combating this infection.
By spreading awareness and ensuring immunization, we can protect vulnerable populations and reduce the global burden of pertussis.
